New York, Sept. 19.- Senator Vest was interviewed in regard to his reported change of views on the silver question. Ho said: "I know absolutely nothing of the published report, and the allcged conversation never occurred. During my stay abroad no one approaohed me on the subject. I have not left the ranks of free coinage advocates and my adheronce to the principies which I have always advocated is unchanged. I flrmly believe in the f uil and unlimited use of silver against the single gold standard."
